1974—1976年我们在繁殖金小蜂时,除用棉茧繁殖外,还采用了部分纸茧进行繁殖,因而金小蜂的繁殖数量由往年的200—300万头逐步增加到1976年的700多万头,满足了本场的需要。通过三年的实践,我们体会到用红铃虫纸茧繁殖金小蜂具有很多优点。 1.取茧省工。纸茧不需剥茧,直接就可采用。1976年我们共用15斤纸茧和12斤棉茧繁殖金小蜂,纸茧仅用去贴纸工5个,而棉茧用去剥茧工150多个,前者比后者节省了170多个剥茧工。
In 1974-1976, when we multiply golden bees, we used some paper cocoons to breed them except reproduction with cotton cocoon. As a result, the number of golden bees multiplied from 2 million to 3 million in previous years to 700 in 1976 Tens of thousands, to meet the needs of this field. Through three years of practice, we have realized that there are many advantages to breeding golden bee with paperworm red bollworm. 1. Take cocoon workers. Paper cocoon without stripping cocoon, can be used directly. In 1976 we shared 15 pounds of paper cocoons and 12 pounds of cotton cocoon breeding gold wasps, paper cocoons only to paste paperwork 5, and cotton cocoon to stripping cocoon workers more than 150, the former than the latter to save more than 170 stripping Cocoon workers.
